I initially didn't have `use` and found it less clear. I also think "use changeset-centric" sounds weird. Maybe just `changesetcentric` as you said then, but that also seems unclear. It feels like we're working around https://phab.mercurial-scm.org/D2010. I can accept that we don't want to queue that, but I don't really like any of the shorter names either. Maybe the current name is fine given the docstring?
